I edited my above post to add some things I forgot before replying.
Lucky Teacher is a superior game. Although two of the main girls in this game are much hotter, and the drawn scenes are much better, Lucky Teacher has more content, better content, more scenes, more girls, and a better gameplay loop. I really don't like this game's inventory/mantra management system. It looked good in the previews, but in practice it is poorly executed and a bit messy. They're improving it, they said.
Lucky Teacher is an older game though, so maybe in time this one will surpass it. Unfortunately devs are going the piecemeal route, little-by-little updates, with some "big" paid DLC's coming. I have to wonder what they think is "big" considering this game isn't. But we will see. I'm hopeful they'll improve based on user feedback.
I've spent many hours in this game digging into it deeply, because I want to like this game, but some questionable choices by the devs and a sloppy release has me feeling it's not that great.
